In the new issue of Regulation, economist Pierre Lemieux argues that the recent oil price decline is at least partly the result of increased supply from the extraction of shale oil. The increased supply allows the economy to produce more goods, which benefits some people, if not all of them. Thus, contrary to some commentary in the press, cheaper oil prices cannot harm the economy as a whole.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

Guest Worker Visas Can Halt Illegal Immigration

There is a trade off between the number of lower skilled guest worker visas and the number of unauthorized immigrants. More lower skilled guest workers means fewer unauthorized immigrants. Fewer guest workers mean more unauthorized immigrants. We just have to look back to the Bracero program to see this relationship.

The number of removals and returns is an approximation of the stock of the unauthorized immigrant population and flows. Many, but not all, of those removed or returned during this time period were funneled into guest worker visas. Beginning with the adoption of the Bracero program and the H2 visa in the early 1950s, there was a flurry of removals and returns whereby many migrants were funneled into the guest worker visa programs. After that, my thesis is that the large numbers of work visas decreased the number of apprehensions by shrinking the pool of unauthorized immigrants and channeling future ones into the legal system. After Bracero was ended in the mid-1960s, the number of removals and returns began a steady increase along with an increase in the stock and flow of unauthorized immigrants deprived of their previous lawful means of entry and work.

The more low skilled guest workers there are, the fewer unauthorized immigrants there are to deport.

One legal worker on a visa seems to be worth more than one unauthorized immigrant worker – meaning a pretty favorable trade off in numbers for those concerned about the numbers of immigrants. In 1954, 1 guest worker visa replaced 3.4 unauthorized immigrants, meaning that one legal worker seemed to be equal to more than three illegal workers. If an important goal of a lower skilled guest worker visa is to eliminate the American economic demand for unauthorized immigrants, relatively few guest worker visas can replace a much larger unauthorized immigrant population.

Increases in Border Patrol and border enforcement are also unnecessary to get this result. By allowing unauthorized immigrants to get the work visas, by not punishing them or employers for coming forward, and by making work visas available to those who want to enter, almost all future and current unauthorized immigrants can be funneled into the legal market without a large increase in enforcement. This was the policy followed in the 1950s and it appears to have worked:

This is not to say that Bracero was a perfect program and that it should be replicated today. There were a lot of problems with it, namely that migrants were constrained in changing employers, migrants were limited to working only in agriculture, and the work visa was annual – all issues that should be fixed in any new lower skilled guest worker visa adopted. A lower skilled guest worker visa is indispensable to vastly reduce or even halt unauthorized immigration.
